Q&A for How to Keep Hair from Curling with Humidity

Unfortunately, thermal styling tools like a flat iron just aren't going to able to defy the humidity. Chemically straightening your hair would be more effective.

Use heavy styling products. They'll weigh down your hair and add an extra layer of protection from the humidity.

Putting your hair into a bun or braids is a good idea, but plain old rubber bands are very damaging to hair, especially curly hair. Consider using hair ties (the fabric covered kind) instead. Also, try getting a satin pillow case, or a cotton pillow case with a very high thread count. The smoother the fabric is, the less it will snag on your hair and cause frizz.

I have the same problem, I put my hair in a ponytail to get it out of the way, or I'll use a straightener on my ends with a good heat protectant.

Use a hair straightener to curl your bangs in the opposite direction from which they tend to curl.

Don't wash it right before you are going out in the humidity. If you flat iron, go out in the humidity long enough for it to get frizzy, then flat iron again. Repeat a couple of times if possible. This will help some. And skip conditioner on really humid days. Just use a premium moisturizing shampoo.

To stop your bangs from curling, have them cut thicker with upward cuts at the ends so they will stay flat. Also it's helpful to spray them with hair spray that is either water resistant or has keratin.

You'd probably have to straighten it again. If you still can't get your hair to stay straight, just put it up in a bun, braid, or ponytail.

If you're going to be outside for most of the day, no. If you're just outside for a few minutes, then likely yes.

Try wetting it down or putting it in a tight plait, which will keep it together.

Apply some shea butter. It will moisturize your hair, make it shiny, and prevent it from curling.

If you have already tried pulling it up in a bun, maybe try putting it in a braid. That way no little hairs can pull out and become frizzy.
